Extramedullary hematopoiesis within endothelial papillary hyperplasia (Masson?s pseudoangiosarcoma) of the tongue

We report the unique association of Masson?s pseudoangiosarcoma (endothelial papillary hyperplasia) and extramedullary hematopoiesis. The lesion was present as a violaceous nodule on the side of the tongue of a 78-year-old man with history of multiple myeloma and long-standing mild anemia. This association between a peculiar form of thrombus organization and extramedullary hematopoiesis has been reported previously only once, in an infant with a cranial hematoma, and raises interesting pathogenetic questions

Osteochondroma of the Thoracic Spine and Scoliosis

Study Design. The case of a 16-year-old patient with an osteochondroma in T11 and scoliosis is reported. Objective. To describe the treatment of an osteochondroma with scoliotic deformity and the imaging methods used for the diagnosis. Summary of Background Data. Osteochondromas arising in the vertebral column are rare. However, spinal involvement is found with some regularity because osteochondromas are among the most common benign tumors of bone. Methods. The clinical history, plain radiographs, computed tomography, and magnetic resonance imaging, and pathologic findings of the reported patient were reviewed. The medical literature also was reviewed. Results. The patient was treated with surgery in an attempt to remove the tumor and correct the aesthetic deformity. The results were satisfactory, with an improvement of the thoracolumbar scoliosis from 45°to 18°. Conclusions. Osteochondromas of the vertebral column may cause scoliosis. Computed tomography and magnetic resonance imaging are necessary for evaluating the origin, size, and characteristics of the tumor. In this case, surgical management involved resection of the tumor and correction of the scoliotic deformity

Pathogenesis and endoscopic findings in H. pylori infection in children

La infección por Helicobacter pylori es una de las causas más frecuentes de infección bacteriana crónica en el ser humano. A través de distintos factores patogénicos (adhesinas, ureasa, proteínas citotóxicas cagA y vacA) puede producir cambios que se pueden apreciar en una endoscopia digestiva alta. Estos incluyen la aparición de lesiones ulcerosas, mucosa en empedrado y palidez alternando con eritema, entre otros. Sus dianas preferentes en la edad pediátrica son el antro gástrico y el duodeno proximal. Este artículo hace una revisión de los hallazgos endoscópicos relacionados con la infección por H. pylori en niños, así como de sus posibles causas y consecuencias clínicasH. pylori infection is one of the most frequent chronic bacterial infections in human beings. Through different pathogenic factors (adhesins, urease, cagA and vacA cytotoxic proteins) it may produce mucosal changes that can be seen in an upper gastrointestinal endoscopy. These changes include, among others, ulcerative lesions, cobblestone mucosa and pallor alternating with erythema. Its favorite targets in children are the gastric antrum and proximal duodenum. This article reviews the endoscopic findings related to H. pylori infection in children and their possible causes and clinical consequence
